HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 510,495, dated December12, 1893.

Application filed May 25, 1893.

To all whom it may concern:

Be it known that l, NILS ZETTERBERG, a citizen of the United States,residing at Belgrade, in the county of Stearns and State of Minnesota,have invented a new and useful Hay-Stacker, of which the following is aspecification.

This invention relates to hay stackers; and it has for its object toprovide certain improvements in stackers of that character which arecapable of being moved from place to place in piling up different stackson a field.

To this end the main and primary object of the present invention is toprovide a portable hay stacker capable of being readily knocked down andagain set up for use, as Well as being laterally adjustable in width tonot only accommodate it to different widths of stacks, but also topermit the same to be carried through gates, over bridges, &c.

With these and other objects in view which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

In the accompanying drawings:-Figure 1 is a perspective view of a haystacker constructed in accordance with this invention. Fig. `2 is avertical longitudinal central view thereof. Fig. 3 is anenlargedpcentral longitudinal sectional view including the connection ofthe extension track with the main track, and the leg support or standardfor the extension track. Fig. iis an enlarged detail sectional view onthe line of Fig. 2.

Referring to the accompanying drawings, A A represent the oppositerunner frames which are adapted to slide on the ground when being movedfrom place to place, but said runner frames may be supported on wheelsin order to insure the more convenient transportation of the stacker,and each of said runner frames is provided with the end uprights B,braced thereto by the brace bars C, and arising from the runners attheir extremities. The end uprights of each runner frame are not trulyperpendicular to the runners to which they are attached, but aredisposed at an upward angle therefrom so that the opposite pairs ofvuprights converge toward each other, thereby forming an open framebetween the same, which approximates the shape of stack or rick formedthere-between. To

Serial No. 475,488. (No model.)

the upper extremities of the uprights B, arising from one of therunners, are attached the slip loops D, projected above the uprights inorder to each removably receive one end of the upper cross beams E,which are held in position in said loops by the securing pins or boltsF, and which rest fiat on the top of the rest plates G. The rest platesG, have the opposite side portions g, thereof, attached to oppositesides of the uprights to which the slip loops are attached, so that thetop portions thereof, on which the cross beams rest, will be disposed ina horizontal plane, thereby supporting the ends of the cross beams E, ina horizontal position.

The other extremities or ends of the cross beams E, are provided withthe off-standing perforated pivot ears or lugs, I-I, which are adaptedto embrace corresponding ears H on the upper extremities of the uprightsarising from the other opposite runner, and pivot pins or bolts I, passthrough the superposed ears, so that one of the runner frames ispivotally attached to one extremity of the cross beams, whereby alaterally spreading adjustment of the stacker frame may be secured. Thelaterally spreading adjustment of the stacker frame permits the same tobe widened or narrowed, as desired, according to the nature of the workor the ground, in case of unevenness, or to permit the stacker to becarried over bridges or through gates, and the same may be held iirm inany adjusted position by means of the sectional adjustable end brace J.The sectional adjustable end brace J, comprises separate perforatedmembers j, pivoted at one end to directly opposite end uprights and heldtogether by the loop j', and said members are held in any adjustedposition by means of a pin or bolt K, engaging any of the alignedperforations thereof.

Suspended from the eyes L, attached centrally to the cross beams E,bymeans of hooks Z, engaging said eyes, is the main longitudinal track M,which is designed to accommodate a wheeled traveler or carrier N. Thewheel traveler N, is of the ordinary construc- IOO tion and accommodatesthe fork rope 0, leading to a suitable power at one end and at its otherend carrying the ordinary hay fork l?,

" which receives its load from one end of thestacker, and carries itover and distributes it onto the stack arranged under the track M. Thetrack M is provided at one end, beyond one end of the stacker frame,with the eye plate Q, which is adapted to removably receive theattaching hook R, secured to one end of the track extension S, and bothsaid track extension S and the main track M, are rabbeted as at s, attheir meeting ends, so as to provide a continuous unbroken line of trackfor the carrier N, to travel on. The other outer extremity of the trackextension S, is firmly supported in position by means of the folding legstandard T, the lower end of which is adapted to rest on the grou nd,and the upper end of which has attached thereto the castingt,providedwith the parallel lugs U, between which is pivoted the open pulley boxV. The open pulley box V, is a part of the loop casting W, which looselyembraces the track extension S, and is free to slide thereon, so thatthe leg standard T, can be adjusted to restin any desired position underthe track extension, to give it the proper support, and when adjusted,suitable guy ropes X, may be run from the loop NV, to the ground. Theopen pulley box V, is disposed below the loop portion W,of the casting,and accommodates inside thereof the rope pulley Y, over which passes thefork rope O, which leads under the ground pulley O', and thence to thehorse or other power for operating the traveler. `It is to be observedthat the journal of the rope pulley forms the pivot for the loop castingW, or at least the pivot for the leg standard T, which may be folded upagainst the track extension S, when it is detached from the main trackof the stacker, and it will be further observed that the disposition ofthe rope pulley, not only provides fora convenient arrangement of therope, but places the strain therefrom directly on top of the said legstandard, as will be easily understood.

The construction of stacker herein described not only provides for theportability and adjustability just described, but at the same time issuch that the several parts of the stacker may be easily separated fromeach other and put in a knock down condition, and quite as easily set upagain for use, and I will have it understood, that changes in the form,proportion and the minordetails of construction may be resorted towithout departing from the principle or sacrilieing any of theadvantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

1. In a hay stacker, the opposite runner frames capable of lateraladjustment to and from each other, the top cross beams removablyconnecting the upper ends of the opposite frames together, a sectionaladjustable brace connecting the two runner frames, the track suspendedfrom the cross beam, and the hay carrier, substantially as set forth.

2. In a hay stacker, the opposite runner frame, having end uprights,cross beams removably attached tothe upper extremities of one pair ofuprights and pivotally to the opposite pair, a track suspended from saidcross beams, and a hay carrier arranged to travel on the track,substantially as set forth.

3. In a hay carrier, the opposite runner frames having end uprights,slip loops attached to the upper extremities of one pair of uprights,pivot ears attached to the cor-4 responding extremities of the oppositepair of uprights, cross beams removably fitted at one end into the sliploops of one pair of uprghts and having at their other ends pivot earspivotally connected to the ears on said uprights, an adjustable bracefor the two runner frames, the track suspended from said cross beams,and the hay carrier mounted to travel on said track, substantially asset forth.

4. In a hay stacker, the opposite runner frames having end uprights,slip loops attached to the upper extremities of one pair of uprights,rest plates attached to the saine uprights and having horizontal topportions,-

cross beams removably fitted atone end into said slip loops and restingon said rest plates and having their other ends pivotally joined to theupper extremities of the other pair of uprights, a sectional adjustablebrace connecting the two runner frames, a track suspended from saidcross beams, and a hay carrier mounted on the track, substantially asset forth.

5. In a hay stacker, the combination, with the connected runner framescarrying top cross beams, of a main track suspended from said main topcross beams and having an eye plate at one end, a track extension havingan attaching hook at one end adapted to removably engage the eye plateof the main track, and a folding leg standard adjustably connected tothe track extension, substantially as set forth.

6. In a hay stacker, the combination with the connected runner framescarrying top cross beams; of a main track suspended from said top crossbeams and having an eye plate at one end, a track extension having anattaching hook at one end adapted to removably engage the eye plate ofthe main track, a loop casting loosely embracing the track extension andhaving an integral depending open pulley box, a rope pulley journaled insaid open pulley box, a folding leg standard having parallel attachinglugs at its upper extremity adapted to pivotally embrace the open pulleybox, the hay carrier moving over the aligned tracks, and the fork ropeadapted to pass over the rope pulley in said open pulley box,substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
